Twisted Pair (TP) Cable Advantages
Twisted pair cable is much smaller, lighter, more flexible, and less expensive than coaxial
cable. These TP products make cable runs simpler and less cumbersome. Termination of the
cable with RJ-45 connectors is simple, quick, and economical.
Transmission Distance
•
The maximum distance is determined by the frequency and resolution of the signal
that is input to the transmitter. The table below specifies the recommended maximum
transmission distances and transmitter Pre-Peak switch positions (see item
e
on
page 7
) using Extron Enhanced Skew-Free AV UTP cable or UTP CAT 5, 5e, or 6 cable,
terminated with RJ-45 connectors.

NOTE:
It is possible to exceed the recommended distance; however, image quality may
be reduced.
NOTE:
The MTP units are designed for and perform best with Extron Enhanced Skew
Free AV cable terminated in accordance with the TIA/EIA T 568 A wiring
standard. CAT 5, 5e, and 6 cables are acceptable, but less preferable. Extron
also recommends the use of preterminated and tested cables. Cables terminated
on site should be tested before use to ensure that they comply with Category 5
specifications.
NOTES:
•
The recommendations shown in the table above apply for a single transmitter
and receiver and for a transmission daisy chain. For example, the maximum
suggested range for 1024 x 768 video is 300 ft. (90 m) with Pre-Peak off
and 500 ft. (150 m) with Pre-Peak on whether the system consists of one
transmitter and one receiver or a transmitter and three daisy-chained receivers.
•
For a daisy-chained system, the first receiver in the chain must be at least
100 ft. (30 m) from the transmitter when the Pre-Peak switch is on.
•
For a daisy-chained system, any receiver in the chain closer than 350 ft.
(105 m) may experience some form of over-peaking when the Pre-Peak switch
is on. An overpeaked image may appear bloomed.
